Comparative Evaluation of Baska Mask and LMA Supreme in Patients Undergoing Short Surgical Procedures Under General Anaesthesia.

ABSTRACT

Supraglottic airway devices (SAD) are used for airway management in patients undergoing general anaesthesia, averting the need of tracheal intubation. Laryngeal mask airway is easy to insert and can be inserted by paramedics also in case of emergency. Here we primarily compared the efficacy of Baska Mask and LMA supreme in terms of ease of insertion. The secondary outcome was assessment of oropharyngeal seal pressure and post op laryngopharyngeal complications. MethodsA sample size of 30 was calculated in each group. Patients were divided into 2 groups, Group B and Group S. After giving premedication, Anaesthesia was induced with propofol 3 mg/Kg and anaesthetic depth will be deepened with 2% sevoflurane in oxygen using bag mask ventilation. An appropriately sized prior lubricated Baska mask and LMA supreme was inserted in Group B and Group S, respectively and ease of insertion was assessed. ResultsThe BM was successfully inserted in 23 patients (76.6%) in the first attempt and LMA supreme was successfully inserted in 29 patients (96.6%) in the first attempt. The difference was found to be statistically significant (P= 0.028). BM created a significantly higher oropharyngeal seal pressure than the LMA supreme group (P < 0.001). No significant difference in postoperative laryngopharyngeal complications was observed. ConclusionsFrom the present study, it is concluded that LMA supreme is easier to insert than BM. The BM creates higher oropharyngeal seal pressure and thus provides a better airway seal than the LMA supreme. The incidence of postoperative laryngopharyngeal complications is similar in both the groups.
